Title: A Simple Method for Isothermal Titration Calorimetric Data Analysis. Authors: A.A. SABOURY Abstract: A Simple method was introduced for isothermal titration calorimetric data analysis. This method was applied to the binding of monosaccharide methy1 α-D-mannopyranoside to concavalin A at pH 6.9 and temprature of 25°C. The disassociation binding constant (K) and the molar enthalpy of binding (ΔH) were 0.135 mM and -28.47 KJ/mol, respectively. These results were markedly consistent with the results obtained from previous method.

Title: Potable Water Quality Characteristics of the Urban Areas of Peshawar (Pakistan) Part 1: Tubewell Water. Authors: AZIZ-UR-RAHMAN; A.R.KHAN Abstract: Potable Water quality of the urban areas of Peshawar was monitored for various physical and chemical parameters. The importance of this reference data, related to the water quality of Peshawar was felt after spreading of some water borne diseases, mainly diarrhea in one of the areas of Peshawar (Sufaid Dheri) during the summer 1999 in which a few people had died and several were hospitalized. Forty three water samples from different tube wells of the urban areas of Peshawar were analysed for pH,TDS, TSS, electrical conductivity, turbidity, total hardness, calcium magnesium, alkalinity, chloride, nitrate sodium and potassium. The concentration of these analytes were found in the ranges; pH (6.0-7.9), TDS (180.20-351.82 mg/l), TSS (1.05-4.21 mg/l), Electrical conductivity (200-390 mg/l), turbidity (0.3-2.1 NTU). total hardness (126.17-458.9 mg/l) calcium (21.81-90.90 mg/l), magnesium (12.50-80.72 mg/l), bicarbonates (132-244 mg/1) chloride(10.04-54.45 mg/1) ,sulphate(16.43-80.28 mg/1),nitrate (1.8-35.2 mg/l), sodium (7.9-74.6 mg/1), and potassium (1.6-6.2 mg/1), Mean Concentration values of the different analytes of Peshawar water were also found. Average values of pH (7.06+-0.45), TDS (284.57+-51.16 mg/1), TSS (2.27+-1.03 mg/1), Electrical conductivity (315.58+-57.28 mg/1), turbidity (0.73+-0.42 NTU, total hardness (306.23 +-70.64 mg/1) , calcium(61.61+-12.23mg/1), magnesium(36.03+-13.47mg/1),bicarbonates(187.84+-25.87mg/1),Chloride (31.41+-10.55 mg/1), sulphate (49.43+-16.15 mg/1), nitrate (19.21+-10.58 mg/1), sodium (28.92+-9.95 mg/1), and potassium (3.65+-1.17 mg/1), Alkalinity (due to hydrooxide and carbonate) and nitrates were found absent. All the analytes were found to be within the WHO possible limits. This paper concludes that, waters of all the tube wells of Peshawar (understudy) are safe for human consumption provided the supply lines and the storage tanks are prevented from being contaminated. A lowering trend in the pH of underground waters of Peshawar was seen, the reason of this was not found. The results presented in this paper also contradict the previous statement about the nitrate concentration in the tube well waters of Peshawar to have been decreasing.

Title: Review on the Technology for the Production of Activated Carbons Authors: TANZIL H. USMANI; M. TM-HR MOTAN; A.H.K. YOUSUFZAI Abstract: The term activated carbon in its broadest sense includes a wide range of carbon-based materials prepared to exhibit a high degree of porosity and an extended interparticulate surface area. These are obtained by combustion, partial combustion, and thermal decomposition of various carbonaceous substances of cellulosic, mineral and polymeric nature. Activated carbon may be in powdered, granular or fibrous forms. The granular form is characterized by large internal surface and small pores, whereas the finely divided powdered form is associated with larger pore diameters but a smaller internal surface. Fibrous activated carbons Ire particularly outstanding in their physico-mechanical properties and high chemical resistance. In this article, successive stages of technology development, of activated carbons in powdered, granular and fibrous forms from precursors of different origin, have been thoroughly reviewed.
